XenServer performance alerts
Now you can decide which VMs or hosts you want to monitor, and XO will send you an email if some thresholds are reached. Let's see how it works!
New year, new features in Xen Orchestra: "performance alerts". In short, you can decide which VMs or hosts you want to monitor, and XO will send you an email if some thresholds are reached. Let's see how it works!

And indeed, we had an email!
If you click on the link, you'll be redirected directly to the VM stat view :)
Also, when the alert is finished, you'll be also notified:
More to come!
Right now, you can create any number of alerts, regarding CPU or memory. But we'll add more features soon!
